Olafur Eliasson (*1967 in Copenhagen) is one of the most famous artists of his generation. In his installations, the Icelandic artist deals with aspects of Land Art, transplanting his contemporary interpretations of it to museums and thoughtfully planned park settings. The scented tunnel created for Wolfsburg, Germany's Motor City, elucidates a fascinating interplay of nature and technology, where multiple sensory impressions combine to form a whole in the observer's perception. This publication documents Dufttunnel throughout an entire season. The various blooming phases of different plants are accompanied by scientific and art-historical interpretations of the Dufttunnel phenomenon.
